Disclosed are embodiments that determine a location of a first wireless device based on estimates of two other wireless devices. Each of the other wireless devices is assigned or defines its own plurality of regions. Each wireless device estimates a location of the first wireless device with respect to its assigned or defined plurality of regions. One of the estimates is then translated to the other device's plurality of regions. The two estimates are then combined to estimate the location of the first wireless device.
Legal claims defining the scope of protection, as filed with the USPTO.
2. The system of claim 1, wherein the first reference device and the second reference device are access point (AP) devices.
3. The system of claim 1, wherein obtaining the location of the first reference device comprises determining the location of the first reference device based on phase differences of signals exchanged between the first reference device and the second reference device.
4. The system of claim 3, wherein determining the location of the first reference device based on phase differences of signals exchanged between the first reference device and the second reference device comprises comparing expected phase differences of signals to be received by the second reference device and measured phase differences of signals received by the second reference device.
6. The system of claim 1, wherein aggregating the first location estimate of the wireless device and the mapped second location estimate of the wireless device comprises averaging the first location estimate and the mapped second location estimate.
9. The method of claim 8, wherein the first reference device and the second reference device are access point (AP) devices.
10. The method of claim 8, wherein obtaining the location of the first reference device comprises determining the location of the first reference device based on phase differences of signals exchanged between the first reference device and the second reference device.
11. The method of claim 8, wherein determining the location of the first reference device based on phase differences of signals exchanged between the first reference device and the second reference device comprises comparing expected phase differences of signals to be received by the second reference device and measured phase differences of signals received by the second reference device.
13. The method of claim 8, wherein aggregating the first location estimate of the wireless device and the mapped second location estimate of the wireless device comprises averaging the first location estimate and the mapped second location estimate.
16. The non-transitory computer-readable media of claim 15, wherein obtaining the location of the first reference device comprises determining the location of the first reference device based on phase differences of signals exchanged between the first reference device and the second reference device.
17. The non-transitory computer-readable media of claim 16, wherein determining the location of the first reference device based on phase differences of signals exchanged between the first reference device and the second reference device comprises comparing expected phase differences of signals to be received by the second reference device and measured phase differences of signals received by the second reference device.
19. The non-transitory computer-readable media of claim 15, wherein aggregating the first location estimate of the wireless device and the mapped second location estimate of the wireless device comprises averaging the first location estimate and the mapped second location estimate.
